The e2-pod Intelligent Drive System comprises of a compact,
lightweight 250W geared brushless hub motor that is fitted
in the front wheel. This connects, via waterproof cable
connectors, with a cable from the bottom bracket torque
sensor, to the machined aluminium pod, clamped securely
on to the head tube. Also feeding into the e2-pod are the
cables from the brake lever sensors. All these items along
with the Bosch battery, add around 3.9kg to the weight of the
unpowered bike.
The e2-pod, battery latch, pod side lever, Bluetooth controller
and cradle components are all CNC-machined from solid
billets of Peraluman 470 Aluminium Grade 5083/AIMg 4.5Mn,
polished, anodised and weather-sealed.
For riding on the flat, or when power assistance is not required,
the battery can be left off the bike.
State of the art surface-mounted technology is used
throughout. Smooth but responsive digital control of the
motor is assured by a 32-bit ARM® microcontroller. This can
access 16 Megabytes of flash memory to improve system
performance intelligently. Highly efficient power supplies are
used to minimise battery usage. A 3-axis accelerometer uses
micro electromechanical technology to determine how steep
the hill/gradient is at any moment and automatically adjusts
power accordingly.
Three fully compliant USBC ports are located on the side of
the e2-pod for phone charging.
